Energy Trial FAQs
How will the trial help the community use local energy more efficiently? The trial is opening up the relationship between energy generated and consumed behind a substation (local energy on the low voltage network) and generation & demand of energy on the high voltage network. The trial will examine the data on the energy flows behind a substation to ascertain whether more capacity (low carbon technologies like solar PV, air source heat pumps and electric vehicle chargers) can be added without having to reinforce the local substation. The community will be rewarded for avoiding 'stress events' on the local grid at times of peak energy usage and for agreeing to participate in the trials. During the trial, we will test how homes with solar panels, batteries, heat pumps, and electric vehicle chargers can better manage energy use, ensuring power flows smoothly in the local area. This could make it easier and quicker for more homes to install low-carbon technologies in the future.
What is local energy? Local energy is electricity generated close to where it is used, typically from renewable sources like rooftop solar panels, small wind turbines, and smart batteries connected to the local low-voltage network. In contrast, traditional energy comes from large, distant power stations—such as nuclear plants, offshore wind farms, or coal and gas power stations—which supply electricity to communities via the national grid. This system results in energy losses as electricity travels long distances, making it less efficient and often less clean. Local energy, by comparison, is cleaner and more efficient because it is generated and consumed within the community. In this trial, we will focus on solar energy produced by homes on the same local power line (or feeder) from the substation. Because this energy doesn’t travel across the wider national grid, it should be cheaper for you to buy excess solar from your neighbours while allowing them to earn more than if they sold it to a national supplier. This approach benefits both individuals and the wider community.
Who can join the trial? The trial is based on feeder lines—the copper wires that run from a local substation to homes and businesses. Your trial community consists of everyone connected to the same feeder line, meaning that the community is clearly defined Only residents and businesses on the selected feeder lines will be invited to take part.
